Often us readers enter a trance and the book which we’re reading is the only thing on our mind. I used to be like this with most books when I was in middle school but now due to academic pressure I do not invest my entire time to a book. Lastly, the Divergent trilogy took me the shortest time to complete- I finished the entire series in three days.
Animal farm. I read the entire book in a little over 2 hours. It was good.
